ST Trackparts BMW E36/E46/E9x Motorsport Wheel Studs Conversion Kit M12x1.5

The ST Trackparts wheel studs conversion kit is engineered to facilitate the use of spacers with varying thicknesses without the need to change wheel bolts repeatedly. This feature significantly streamlines the process of wheel removal and installation, enhancing efficiency and convenience.

Constructed from high-quality 10.9 grade steel, this kit is designed to meet the rigorous demands of motorsport applications while maintaining full safety and reliability for street use. The wheel nuts are specifically designed to prevent the socket wrench from contacting the wheel surface, minimizing the risk of damage during rapid wheel changes.

The kit offers two stud lengths: 75mm and 90mm. The 75mm studs accommodate spacers up to 15mm thick, whereas the 90mm studs support spacers up to 30mm. This versatility ensures compatibility with a broad range of spacer configurations.

Two finish options are available: a black finish providing an OEM appearance, and a copper-plated finish that enhances corrosion resistance and durability, extending the lifespan of the components under various conditions.

Installation is straightforward, requiring only an Allen key for secure fitting. The comprehensive kit includes:

• 20 wheel studs (75mm or 90mm)
• 20 wheel nuts (available with optional copper plating)
• Loctite threadlocker

This conversion kit is compatible with all BMW models featuring an M12x1.5 thread, including but not limited to BMW E36, E46, E9x, E6x, E8x, Z3, and Z4 series, encompassing M3, M5, and M6 variants.
